Those who suffer from sexsomnia have confusional arousals and rarely remember the event. People who have a history of doing other sleep activities such as sleepwalking or sleep talking are more likely to exhibit sexsomnia episodes. Factors that may increase episodes of sleep sex are alcohol, sleep deprivation or even sleep apnea and other sleep disruptions. Sexsomnia episodes could be triggered by the contact with bed partner. In some cases sexualised movements during sleep could be caused by sleep related epilepsy which results in sexual arousal, thrusting and orgasms. Simple sexualised movements could be also associated with REM sleep disorders.
Sexsomnia is a disorder that affects males and females. Isolated reports exist about men and women who have had sex with strangers during the sleep period; in cases where memory of the sexual act is not retained, the detection of used condoms and semen stains on the bed the morning after the sexual incident are signs of the affliction.
Sexsomnia can occur with other sleep disorders such as sleepwalking, sleep apnea, night terrors and bedwetting and can be triggered by stress, previous sleep deprivation and excessive consumption of alcohol or drugs.
Diagnosis: Sleep sex often goes undiagnosed because of feelings of shame or embarrassment. When it is reported it is usually by a sleep partner of someone who has sexsomnia. Then to verify the diagnosis, polysomnography is done during a night in a sleep lab, which confirms whether the patient is truly asleep while performing these sexual acts. Also, the diagnosis of sleep sex is difficult because most people do not come forward with their nocturnal activities as they are unaware of it. The majority of cases come to light only after criminal charges have been filed.
Treatment: Clonazepam has been used as a first line of treatment for this condition

On 30 November 2005, a Toronto court acquitted a man of sexual assault after he was diagnosed with sleep sex disorder, although prosecutors filed an appeal of the acquittal in February 2006. The Ontario Court of Appeal upheld the acquittal on 7 February 2008.
